Title: Improvements in Lifts or Elevators.
Inventor: HARKNESS CHARLES ASHERLEY
Filed: 1900-03-27
Granted: 1900-04-28
Abstract: 5732. Harkness, C. A. March 27. Lifts.-Relates to apparatus for (1) locking the starting - mechanism when the cage is at a floor and a well door is open ; (2) automatically stopping the cage, either instantaneously or when it arrives at the next landing, upon the opening of a well door. The hand-operated shaft c<1>, Fig. 1, carries outside the cage a disc c<3> with a peripheral recess which comes opposite to the hooked end of a lever d when the cage is at rest. This lever is normally held in its inoperative position by a weight d<2>, but, when a well door f<4> is opened, a circuit is closed which includes an electromagnet e, which, acting upon the lever d, pulls it down and thus locks the starting-mechanism. A rocking starting-shaft may be locked in the same way. When the cage is controlled by means of a standing line, automatic stoppage of the cage, in the event of a well door being opened, is effected as follows :-The opening of a door closes the circuit of an electromagnet e, Fig. 6, which raises a toggle-lever h<2>, h<2>. The outer end of this lever is fitted with a cam h, which, as it is forced outwards, jams and operates the standing rope b<1>. The operation of the magnet e may throw forward arms which act only on stops fixed to the standing rope at the various landings. A push-button g is placed in the cage, so that the attendant can by its means break the circuit of the locking-mechanism.

Granted: 1900-07-21
Abstract: 10,295. Froehling, H., Fleming, J. S., and Whitlook, J. G. June 5. Sulphur.-Sulphur is obtained from sulphur-bearing ores by distilling the ores in a neutral atmosphere but with the admixture of a limited quantity of oxygen. In the explanatory drawing, pyrites are charged into a retort 1, which is heated by a furnace 2. The products of combustion pass to a stack 3 having a damper, and a portion of these products mav be withdrawn bv the tube 4, 5. When about one-half the sulphur present has passed off, a neutral gas, such as that collected by the tube 4, 5, is passed into the retort by the tube 6, and afterwards a regulated amount of oxygen or air by the tube 7. Additional sulphur is now given off, iron oxides remaining in the retort. The vapours given off during the process pass by a tube 9, into which a steam pipe 8 enters, to a condenser 10 having in its upper part baffle-plates 11 with openings 21. Any uncondensed products pass by the tube 12 to a tower 13 packed with broken limestone 19, through which water is circulated by a pump 18, tanks 14 and 16, and tube 17.

Granted: 1902-03-06
Abstract: 12,272. Lake, H. H., [Krupp Grusonwerk, F.]. June 15. Moulding a r t i - ficial - stone blocks, slabs, &c.-Relates to the manufacture of artificial stone blocks, slabs, &c., for paving and other purposes, by means of hydraulic presses. The hydraulic cylinder a is fitted with a piston b carrying a stamp or compress- ing - die c, which slides in a mould- ing-box d carried by a lever e. A slide h is formed with a large aper- ture or receptacle k, and a small aper- ture l, and also carries the upper die m. Hoppers f and g hold the body material and coloured f a c i n g- material respec- tively. A drum q is provided with external or internal cam grooves or surfaces for effecting the movements of the slide h, lever e, and of the pressure and exhaust valves of the press. At the commencement of the operation, the piston b or die c are situated slightly above their lowest positions. The box k receives a charge of body material from the hopper f, and transfers it to the mould d. While the material is being delivered to the mould, the receptacle l receives a charge of facing-material from the hopper g, and, on the return stroke of the slide h, the facing-material is spread over the body material in the mould, the die c having previously descended to its lowest position. The die m is then brought above the mould, which is lifted by the lever e to engage the die closely. The piston b rises, and the material is compressed to form the slab or block. The ex- haust valve next opens slightly, and the slide h moves towards the right, after which the slab or block is pushed upwards out of the mould, and is discharged from the machine by the slide on its next advance. The cam ways and surfaces are readily removable from the drum, so as to enable the movements of the die c, slide h, &c. to be varied to suit blocks of various dimensions.

Abstract: 15,135. Cordner, R. A. July 25. Lathes.-Relates to variable-speed and freewheel mechanism for cycles, applicable also for lathes &c. The chain-ring E carries epicyclic pinions which gear with an internally - toothed ring b<4>, fixed to the hub B of the bicycle wheel, and with a spur-wheel D mounted co-axially with the hub. By means of a clutch-sleeve C in sliding engagement with it, this wheel may be locked either to a clutch-member a formed on the fixed axle A, when the gearing comes into action, or to the clutch-member b secured to an extension of the hub, when the gearing is locked and the hub is rotated at the same speed as the chain-ring. In the intermediate position, the sleeve C is free from both a and b. The sleeve is moved to and fro by an arrangement of the same nature as that described in Specification No. 24,703, A.D. 1899, i.e., it rotates in a ring c', which has radial studs in engagement with inclined slots in the casing c' and can be turned by means of a telescopic arm c<7>, c<8> passing through a slot in the side of the casing from any convenient point. The chain-ring is in two parts connected by a ratchet-clutch which gives a free wheel on the high gear. When the clutch-sleeve is moved to set the low gear in action, its bevelled end pushes that pawls outwards by means of radial studs e so that the parts are locked for rotation in both directions. Ball bearings may be used throughout as shown.

Granted: 1902-07-17
Abstract: 16,307. Statter, J. G. Aug. 14. Motor road vehicles.-Consists in propelling the vehicle through the medium of pneumatic transmission. For this purpose any suitable form of internal-combustion engine is used as a prime motor, but, instead uf using it directly to propel the vehicle, it is employed to compress air. The compressed air is then employed to work an air engine the function of which it is to propel the vehicle. A portion of the compressed air is also stored in an accumulator or reservoir, whence it can be withdrawn to work the air engine when the prime motor is not working. Means are also employed to gear the expansion engine and prime motor together so that the prime motor may propel the vehicle, or the expansion engine be used to start the prime motor. Fig. 3 shows a vertical section, and Fig. 4 a plan, of the combined motors, compressor, and gearing. The cylinders 1, 2 of the petrol engine drive the crank shaft 3, whereby the compressor piston in the cylinder 4 is worked. The air-engine cylinders 5, 6 drive the crank shaft 7. This, through a toothed wheel 34 and an idle wheel 35, which can be put in and out of gear, is capable of driving the shaft 3 through a wheel 36, which may be connected to the shaft 3 by a oneway or other clutch. In order to cool the primemotor cylinders and heat the compressed air, the air is passed through the cylinder jackets 14 on its way to the air engine. The air may also be otherwise heated by a tubular apparatus and burner, or by the oil-engine exhaust. The air on the way to the reservoir may be cooled in a tubular cooler.
